On the 9th November, the expedition, which had long been struggling over precipitous mountains and through deep _cañones_, emerged upon the plain, and for a moment all considered the difficulties of the journey at an end. The real gain was confined to the howitzers, which, dragged by main force of men and mules over a terribly rugged country, had by this time had every part of their running gear repeatedly broken and replaced. The artillerymen rejoiced at the level which lightened their labour. It was, however, but an exchange of one set of difficulties for another. Grass ceased when the mountains were left behind, and the mules were fain to feed on willow and cotton-wood. And soon there were short commons for men as well as for beasts. Their first day's march over the plain brought them into the vicinity of two Indian tribes of a very different stamp from the predatory Navajos and perfidious Apaches. The Maricopas and Pimos almost realise those virtuous and heroic savages whom we had hitherto thought to exist nowhere but in Fenimore Cooper's novels. They gallopped into the American camp in a frank confident style, delighted to find they had to do with white men instead of with their enemies the Apaches, of whose approach a report had been spread. There was a Pimo village nine miles off, and in three hours its inhabitants crowded into the camp, laden with corn, beans, honey, and water-melons, and opened a brisk trade. It was Mr Emory's observing night, but the throng, and, the perpetual galloping to and fro, interfered greatly with the correctness of his observations. He was struck by the unsuspicious character of these people, who would leave their packs in the camp and absent themselves for hours. Theft was apparently unknown amongst them. With the mounted party, which first came in, was a man on foot, who appeared able to keep pace with the fleetest horse, and who, on recovering his breath, announced himself as interpreter to Juan Antonio Llunas, chief of the Pimos. With him for a guide, Mr Emory and other officers visited some neighbouring ruined buildings, concerning whose origin he could give them no information except a wild tradition in which he himself did not believe. They then proceeded to the Pimos village, the interpreter going a pace which kept their mules at a long trot.
